Survey finds that most people think poverty is why pollution disproportionately affects Black people, despite evidence that racism is the major cause. | Continue reading
A laboratory has been growing 12 populations of E. coli since 1988 — this year the cultures will get a new custodian. | Continue reading
A retracted paper highlights chemistry’s history of trying to avoid the expensive, toxic — but necessary — catalyst. | Continue reading
Wireless millirobots are promising as minimally invasive biomedical devices. Here, the authors design a magnetically actuated amphibious millirobot that integrates spinning-enabled locomotion, targeted drug delivery, and cargo transportation by utilizing geometrical features and … | Continue reading

Wave-based analog signal processing has been challenging for complex nonlinear operations such as data forecasting or classification. The authors propose here an analog neuromorphic platform for optical wave-based machine learning characterized by energy efficiency, speed and sca … | Continue reading
Tunable sub-megahertz spectral features are demonstrated without resonators. The approach, which exploits gain-enhanced polarization pulling in a twisted birefringent medium, may be useful in applications such as microwave photonic filters, slow and fast light, and optical sensin … | Continue reading
Mainstream personalization methods rely on centralized Graph Neural Network learning on global graphs, which have considerable privacy risks due to the privacy-sensitive nature of user data. Here, the authors present a federated GNN framework for both effective and privacy-preser … | Continue reading
Obloj and Zenger use data on US academic salaries to find that pay transparency decreases inequity (including gender pay gaps) and pay inequality, and also reduces the relationship between pay and performance. | Continue reading
Raj and colleagues show that ERX-41 inhibits lipase-independent functions of LIPA and induces ER stress in different tumor types, providing a therapeutic strategy in PDX models of pancreas, ovarian and triple-negative breast cancer. | Continue reading
Some British researchers who had secured Horizon Europe funding have already been told that their grants will be cancelled. | Continue reading
Researchers are learning more about how the SARS-CoV-2 coronavirus stifles smell — and how they might revive it. | Continue reading
Companies commonly use renewable energy certificates to report progress towards emission reduction targets. However, this use of certificates is unlikely to result in actual emission reductions, which undermines the credibility of corporate emission reduction claims and their ali … | Continue reading
Based on genomic data, the Galapagos giant tortoise species native to Fernandina Island appears to be alive and well, survived by at least one female after being considered extinct since 1906. | Continue reading
Detection of an axial Higgs mode by quantum pathway interference reveals an unconventional charge density wave phase in RTe3. | Continue reading
Research expeditions find that the caldera’s collapse exposed huge amounts of hot magma to water. | Continue reading
Controlled use of fire for subsistence and smallholder livelihoods has undoubtedly shaped ecosystems but we have limited research on the practices and extent. This analysis of nearly 600 case study locations finds fire use is changing in ways that could pose risks to smallholder … | Continue reading
Geographer Gregor Luetzenburg uses the latest iPhone’s LiDAR scanner to create 3D models of cliff surfaces. | Continue reading
Covering 10% of the world’s hydropower reservoirs with ‘floatovoltaics’ would install as much electrical capacity as is currently available for fossil-fuel power plants. But the environmental and social impacts must be assessed. | Continue reading
Here the authors demonstrate the use of zinc isotopes (δ66Zn) to geochemically assess trophic levels in extant and extinct sharks. They show that the Neogene megatooth shark (Otodus megalodon) and the great white shark (Carcharodon carcharias) occupied a similar trophic level. | Continue reading
Higher-order sequence learning using a structured graph representation - clone-structured cognitive graphs (CSCG) – can explain how the hippocampus learns cognitive maps. CSCG provides novel explanations for transferable schemas and transitive inference in the hippocampus, and fo … | Continue reading
Rolling up an ancient river delta in Jezero Crater, the rover starts crucial rock sampling. | Continue reading
The country has been increasing research funding for decades, but its rigid, time-bound approach to research assessment is stifling basic science. | Continue reading

Assembly of the hexaploid oat genome and its diploid and tetraploid relatives clarifies the evolutionary history of oat and allows mapping of genes for agronomic traits. | Continue reading
The genetic prehistory of central America has not been well explored. Here, the authors find evidence from ancient DNA from twenty individuals who lived in Belize 9,600 to 3,700 years ago of a migration from the south that coincided with the first evidence for forest clearing and … | Continue reading
Recent work has reported a realization of a time crystal in the form of the Bose-Einstein condensate of magnons in superfluid 3He. Here, the authors study the dynamics of a pair of such quantum time crystals and show that it closely resembles the evolution of a two-level system, … | Continue reading
The nervous and immune systems are tightly intertwined. Deciphering their chatter might help address many brain disorders and diseases. | Continue reading
Haematopoiesis has high clonal diversity up to about 65 years of age, after which diversity drops precipitously owing to positive selection acting on a handful of clones that expand exponentially throughout adulthood. | Continue reading
Researchers with the World Health Organization explain mistakes in high-profile mortality estimates for Germany and Sweden. | Continue reading
Gaussian boson sampling is performed on 216 squeezed modes entangled with three-dimensional connectivity5, using Borealis, registering events with up to 219 photons and a mean photon number of 125. | Continue reading
Ten years after their profession got its name, research software engineers seek to swell their ranks. | Continue reading
The decline might be another sign of politics affecting cross-country scientific collaborations. | Continue reading
A wave of departures, many of them by mid-career scientists, calls attention to widespread discontent in universities. | Continue reading
Genomic analyses of spike glycoprotein genes of European bat SARS-related coronaviruses suggest that furin cleavage sites can be acquired in the bat reservoir via conserved molecular mechanisms, supporting a natural origin of SARS-CoV-2. | Continue reading
